CH. II.] KILL-DEVILS FOR TROUT, 23 
Perch. Of the kill-devils with which I have fished, 
I have caught most Trout with a small brass 
one, which I got at Bala, pretending no resem- 
blance to a fish, but consisting of a short round 
body and two large flanges—in size as well as 
shape like that represented in Fig. 4. The next 
best, which I have principally used when the water 
contained Jack as well as Trout, is made of Gutta- 
percha, the size of (and I believe intended to 
represent) a small Roach, with pectoral flanges, 
and the tail rounded off; the tail, as the thing 
is commonly sold, being only in the way. This 
I have found very useful in some of the Scotch 
lochs, when short of natural bait.
